It seems the property element has no @value attribute and child element

>From OASIS_sca-assembly-1.1-spec-cd01-rev2+Conformance-05.pdf, it's
using the following examples:

<property name="pi" value="3.14159265" />

<property name="pi">
     <value>3.14159265</value>
</property>

But from sca-core.xsd, I noticed:

<complexType name="PropertyValue" mixed="true">
       <complexContent>
          <extension base="sca:SCAPropertyBase">
             <attribute name="name" type="NCName" use="required"/>
               <attribute name="type" type="QName" use="optional"/>
               <attribute name="element" type="QName" use="optional"/>
               <attribute name="many" type="boolean" default="false"
                        use="optional"/>
             <attribute name="source" type="string" use="optional"/>
             <attribute name="file" type="anyURI" use="optional"/>
             <anyAttribute namespace="##any" processContents="lax"/>
             <!-- an extension point ; attribute-based only -->
          </extension>
       </complexContent>
    </complexType>

Anyone has any sense about this? Thanks!
